Question : How to open new browser with URL in Window 2000?

Hi Experts,
I have problem with open new browser with URL from MFC application.
I have used ShellExecute function as below:
HINSTANCE result = ShellExecute(NULL, _T("open"), url, NULL, NULL, SW_SHOW);

This worked fine on XP and VISTA.
But it can not work (Can not browser) with Window2000
Can you help me for this?

Thank in advance!

Thank for all help,
But I have solved with other way.
I checked if the ShellExecute failed to open URL then I do next to get detault IE from window register and try again.
